Electric Radiators, the fast solution for heating needs

Electric Radiators: what do you need to know?

Intervening in the heating plumbing system, in a housing unit is always a synonym of huge masonry works; the installation of an electric product is instead a convenience, because not having to prepare connections makes the electric radiator the ideal product.

Electric radiators can be specially designed to meet the needs of end users who cannot, or do not want to, intervene on their system.

The operation takes place thanks to an electric resistance connected to a safety thermostat; this resistance is immersed in a special thermovector liquid that fills the whole radiator circuit. When the temperature, set in the thermostat, increases, the resistance transforms electrical energy into heat.

There are different types of heating elements, with more or less advanced technologies: from simple on/off (on/off) to those regulated with thermostat and wi-fi control.

Electric radiators are often installed in the bathrooms of homes that also have underfloor heating because of their function as towel warmers.

Electric radiators can be managed with a chronothermostat; this device allows to regulate the temperature in domestic environments, it allows to regulate the on/off of the radiator, to set the timer and the desired time bands. When you are not at home it is not important to keep a high temperature, but it is enough to program the chronothermostat saving a lot of electricity.

How to choose radiator power.

The power of the radiator must be calculated taking various aspects into account. The size of the room to be heated, the average temperature that you want to keep in the room, its position and the type of house in which it is located. These are just some of the information needed to correctly estimate the power of the radiators. It is very important to correctly size the electric radiator to be installed to avoid the unpleasant feeling of cold.

In order to determine which radiator is best suited to the needs of each individual room, you need to calculate the watts required based on the following information:

    Room size (length/depth/height)
    Type of room (living area/ sleeping area/bathroom)
    Building insulation (poorly insulated / very insulated / Class A)
    Minimum outdoor temperature (-20° to +5°)

In the multimedia area of the IRSAP website is available a CALCULATOR that helps to have a rough indication of the watts needed to heat a room. Obviously, to correctly dimension the heating body it is necessary to rely on a professional who performs the correct calculations.




Dual Function Radiators: the ideal solution for mid-seasons.

As the name itself says, "mixed operation radiators" are heating elements connected to the boiler but which, thanks to an additional electrical heating element, can also operate electrically, which means that these radiators can also be used independently of the central heating system, offering greater control and flexibility.

This allows the radiator to be used even during periods when the heating system is off and in mid-season.   

In order to be able to increase the functionality both in hydraulic and mixed mode, without modifying the hydraulic wheelbase, IRSAP proposes the use of special thermostatic valves and space-saving lockshields that allow the insertion of the electric resistance in the manifold, through the valve cover itself (picture 1).

Many of the radiator models with "50mm" hydraulic centerline connections can be conveniently converted into a mixed operation radiator without having to make any changes to the hydraulic connection or wall mounting of the radiator.

At the lower ends of the side manifolds there are threaded holes in which the electrical resistance can be inserted at any time (picture 2).




Range and offer of electrical products: how to choose?

The wide range of IRSAP electric radiators represents the concrete answer to every electric power requirement (250 to 2000 Watt) and to every housing requirement (various models and sizes).

Many electric radiators can be integrated with:

    ON/OFF control (on/off)
    electronic thermostat to regulate the temperature of the radiator
    IR electronic control to regulate the ambient temperature and remote  control for electronic control
    wireless digital electronic control, programmable weekly to manage the ignition, operation and bring the ambient temperature to the desired degree. This wireless control also allows you to reach the temperature set at the desired time through the ITCS (Intelligence Temperature Control System) function by adjusting the radiator's early ignition according to the ambient temperature.

The IRSAP range offers products that range from design models, for those who want a product suitable for an unconventional home with a strong personality, to the more classic bathroom, furniture or multi-column models, versatile and functional suitable for heating and furnishing any domestic environment.


Everything you need to know about electric radiators and new regulations.

IRSAP has embarked on a virtuous path in the green perspective, now better known as ECO DESIGN, working towards product design in accordance with a responsible philosophy from many points of view: environmental first and foremost, but also ethical and social.

The concrete answer to this path is given by the possibility to choose the most suitable product for your needs, respecting the environment and ensuring maximum energy saving in any season of the year.  
The latest generation of electric radiators must comply with current regulations on energy saving, and they also allow a much higher environmental comfort than the same products marketed before 2018. This is thanks to the new temperature controllers including the ITCS (intelligent temperature control system) function.

The ECO DESIGN 2018 regulations make a distinction between towel warmers and electric radiators: towel warmers only have an on/off function; electric radiators can manage temperatures and time slots. .
